The asymmetric unit of the title compound, C(11)H(16)N(2)O(2), contains two independent conformational isomers which show intra-molecular aromatic-imine O-H⋯N hydrogen bonds. In the crystal, neighboring mol-ecules are linked through inter-molecular aliphatic-aliphatic O-H⋯N, aliphatic-aromatic N-H⋯O and C-H⋯O inter-actions into hydrogen-bonded layers parallel to the ab plane.
